I was going to be a mechanical engineer until they gave me my first elective in my Sophomore year. I chose Ceramics, and the next [term/semester?] I transferred to Architecture. But I outlasted 80% of the cohort.

It needs to be wet when it goes together, then bone dry for firing. This is greenware. Low-temp firing creates bisque:

Choosing a Bisque Temperature

Glazed bisque re-fired at a higher temp creates stoneware.

I was reading that site's page about why pottery cracks. They seem to have good information.

How do I keep my shavingcrete from collapsing in the middle?

As successful as anything else I do



Maybe I need more oil on the pan. The brick came out pretty easily, but left a layer on the pan...

...cemented on.

It crumbled all over and I took it to the garbage outside to break up, but the middle did not break easily. I did not attempt to torture test it, I broke off what came easily, and that is what is left.

Actually rectangular pans, more oil, and trying to leave it higher in the middle?

At what point should I be able to turn it over?

You're the one out on the bleeding edge.

Shaving lubricants in the foam? Bubbles too big/random sizes?

In most of the videos I've seen they use a thin mixture that pours and self-levels.

I prefer to think it looks like a 400m DC-3 fuselage with flames painted down the side (to account for the reddish tinge).

My original bricks (with twice the concrete\foam ratio) cured inside for a week and then sat in the oven at 190 for nine hours. One turned out nicely, but I have not done more than put it somewhere safe and quickly see that it does not seem crumbly:

I do not know why this one came out bubbly, but trying to smooth it made it worse!

For some reason, they formed two layers. The crumbly one had a fair amount of water, seemingly between the layers.



I will crop these pictures when I get home, but I appreciate they automatically resize now!

I showed Mom one of the Dome Gaia Gaia Domes and she asked if they were building those in Puerto Rico.

Someone should be. There is a great opportunity to break out of a number of boxes. If she's concerned about PR, show her this:

Bloomberg: How to Rebuild Puerto Rico

It's book-ended by a feel-good story about a fleaweight boxer, but the heart of it is a tale about anarcho-capitalists. It's inspiring.


I think the bubble size wasn't controlled. Don't be put off by the word autoclave in Autoclaved Aerated Concrete. The just means a sterile oven. You might have to powder the aluminum to get small bubbles.
